Niner’s AIR 9 RDO is designed with cross-country racing in mind. With the culmination of over ten years of research, design, and rigorous lab and real-world testing, The AIR 9 RDO is ready tackle your short track, cross-country, marathon, or ultra-endurance goals. The Air 9 RDO is beautiful from the inside out because of Niner’s Carbon Compaction System, which utilizes rigid internal molds for tighter, more consistent carbon compaction and precise wall thicknesses, or more precisely: more strength with less material. The AIR 9 RDO accommodates up to a 120mm-travel fork for stable, precise steering and handling that lets you relax, stay confident, and focus on being fast. The AIR 9 RDO 5-Star is the definition of race-ready. The 100mm-travel RockShox RS-1 fork ensures a phenomenal ride and stiff, precise tracking through even the roughest rock gardens. Niner’s Carbon XC wheels keep you rolling fast and true with a rim profile wide enough that the already-tacky Maxxis Ikon tires deliver the traction and ride quality of a wider, high volume tire. The legendary Shimano XTR 2 x 11-speed drivetrain will wow you with its, incredibly low weight, flawless function, and elegant lines—shifting instantly and precisely in all conditions to send power to the ground as fast as you can produce it. XTR brakes delivers intuitively modulating, diabolically powerful braking to shave that speed before the critical curve so you roll confidently to victory. Niner included their carbon RDO stem, handlebars, and seatpost for the final polish on this jewel of a race rig.
